Question

What is Totipotency?

• A. The capacity to generate a whole seed from any cell or explant.
• B. The capacity to generate plants with higher levels of vitamins and healthier fats.
• C. The capacity to generate somatic hybrids from the naked protoplasts of two different cells.
• D. The capacity to generate a whole plant from any cell or explant.

Hint:

Totipotency is the basis of plant tissue culture and cloning techniques.

Answer 1

The Correct Option is D

Concept: Totipotency is a fundamental concept in plant tissue culture. It refers to the ability of a single cell to divide and differentiate into a complete organism.

Step 1: Define totipotency.
Totipotency is the:
• Ability of a single plant cell
• To regenerate into a complete plant under suitable conditions

Step 2: Analyze options.

• Whole seed → incorrect definition
• Nutritional enhancement → unrelated
• Somatic hybridization → different concept
• Whole plant from a cell → correct definition

Step 3: Final conclusion.
Thus, totipotency is: \[ The capacity to generate a whole plant from any cell or explant \]
